2SS A8 Trans leak after TC

mikey8 · 09-19-2018, 06:39 PM

I got my dealer to replace the TC after they tried changing fluid that lasted a few thousand miles. Got the car back after they changed the TC and no more shudder. Pulled the car out of the garage a few days after and found tranny fluid on the floor. Took it back and they said it was trans cooler line. They fixed that and it was fine for a coupe of weeks. After they fixed it a few weeks later it leaked again. This time I smelled it driving and pulled over and the back of the car is drenched and so was the underside. I had it towed in, and they have had the car for 3 days and cant figure out where the leak is coming from. I can see on my Chevy App that they have test drove it, but how can it be so obvious, and not be able to be found? I checked my VIN and there are no recalls. It all started with the TC replacement. Any suggestions or opinions what may be going on?

They probably messed up the the torque converter to input shaft seal.If that's the case,out she comes again.

Thanks for the reply. They said they checked everything and it’s dry. They’ve test drove it let it idle in the shop and now they are releasing it. They can’t find a leak. I’m at a loss for words after the car was drenched and they can’t figure it out. I’m really disappointed.

They just called me and said they found the leak.... After I suggested what Harold said above they they called me back and said with that much fluid that’s the only place it can be coming from. So they ordered the part and will have my car back to me by next Friday?

If it leaks like that then the front pump seal is bad. Dealership botched the install.

Thanks sir! Not impressed with my dealer. They still have it and are investigating...

well it turned out to be the seal. Not sure which one it was, but it is good now. No shudder and it is dry....
